I'm using mail enable on Windows Server 2008. Recently I changed from a static IP address to dynamic IP and using the DNSExit updater to update the IP address. If I send an email from a email domain on the mail server to say a yahoo email address the email will bounce and I'll receive the below error. My ISP is BT Broadband.
Reason: Mail server for yahoo.co.uk could not be contacted at this time. MailEnable will keep trying to deliver this message and will notify you of any progress.
Reason Code: DNS Server Timeout
Error Number: 1460
Any help is appreciated
